Magna 2 x 15 cab. Questions

[Doomlord]

Hello all;

I just got a SUNN Magna 2x15 cabinet from a friend. I was wondering if it was possible to properly date when it was made. It looks like it's a late 60's model but i'm not sure.
Secondly, the original speakers were replaced
with 2 guitar 15-inch speakers. Are the JBL
D140-F speakers the proper relacements for this cab ?
Thanks in advance for your help.

I also have a Sunn 215s "Magna" 2x15 cab.  I was told mine was circa 1972.  I have 2 JBL K-140 speakers in it.  I was told that the K-140 is basically the D-140 but came out a few years after the D-140.   I think the D140 speakers were used in the 200s 2x15 cab in the 60's.  Either way, my cabinet is being powered by a modern Sunn 300T all tube bass head (now no longer being made as Fender dropped the product line).  I also have a 1967 Sunn 200s head that I use through this cabinet.  The 300T/215s cab set-up is the best bass head/cab set-up that I have ever experienced for larger venue gigs - thunderous earth quaking bass that hits you in the chest.  My band mates noticed the difference immediately.  For smaller rooms I use the 200s head.  The cabinet itself has the 2 handles on one side of the cab, 2 speakers are positioned a little left of center, and 2 baffles are positioned along the right side of the cabinet.  Hold onto that cab - put in some JBL's and you won't be disappointed!

thanks, Randy!

I guess it's more like an early 70's model
than a late 60's

Any other help out there??

I would like at least to know what
year my cabinet was made.

Thanks

It's mid '60s to mid '70s. If you tell us the serial number on the ID plate, or send a photo, we might be able to narrow it down. (Why does thec year matter?)

Hi -

If you have to remove the grille to mount the speakers, it's post 1969; if you have to remove the back to mount the speakers, it's 1969 or earlier.

As far as the 2X15 cabinets, I rather prefer the front-loaded design for sound.  But for appearance and mojo the rear-loaded cabs are beyond cool.  Either sounds fabulous, even with other than JBL's.  To this day, the old Sunn 2X15 cabs are the very best.

The serial # on the back is C004060
I guess it's later than 69 as the speakers
are front-loaded going by the prior info.
Not too important; just wanted to know what
year it was made....its in excellent shape
for its age
